5、seding J2039 MAY2001 Side Turn Signal Lamps for Long Vehicles RATIONALE This document was revised to address the comments received from the ballot of Sep 2, 2008, FEB 2010, APR 2012, no overshoot is allowed. In the case of measurements taken in the flashing mode the reported luminous intensity shall

6、 be the maximum intensity. 5.1.6 Warpage Test on Devices with Plastic Components SAE INTERNATIONAL J2039 Revised JAN2014 Page 5 of 9 5.2 Color The lamp assembly color shall be measured in accordance with SAE J578. 5.3 Plastic Materials The plastic (optical) materials shall be tested in accordance wi

7、th SAE J576. 6. REQUIREMENTS 6.1 Performance Requirements The device when tested in accordance with the test procedures of this document shall meet the requirements of SAE J2139 or as indicated. 6.1.1 Vibration 6.1.2 Moisture 6.1.3 Dust 6.1.4 Corrosion 6.1.5 Photometry 6.1.5.1 The lamp shall be desi

8、gned to conform to the zone total photometric requirements of Figure 1 and its footnotes. The summation of the luminous intensity measurements at the test points in a zone shall be at least the value shown. 6.1.5.2 When a sidemarker lamp is combined with the side turn signal lamp, the side turn lamp

9、 intensity shall not be less than five times the luminous intensity of the sidemarker lamp at any test point of Figure 1 6.1.5.3 If multiple lamps are used for the side turn signal function each lamp shall meet the requirements of this standard. 6.1.5.4 Lamp size, compartment and/or sections do not

10、apply to this standard. 6.1.5.5 Conformance of lamps with LED light sources should use the photometry procedure described in SAE J1889 section 6.1.5 SAE INTERNATIONAL J2039 Revised JAN2014 Page 6 of 9 FIGURE 1 PHOTOMETRIC REQUIREMENTS MINIMUM LUMINOUS INTENSITY (CD) 6.1.6 Warpage 6.2 Color The color

11、 of the light from the side turn signal lamp shall be yellow as specified in SAE J578. 6.3 Plastic Materials The plastic materials used in the optical parts shall meet the requirements of SAE J576. SAE INTERNATIONAL J2039 Revised JAN2014 Page 7 of 9 6.4 Design Requirements 6.4.1 If a side turn signa

12、l lamp is optically combined with a sidemarker lamp and a replaceable multiple light source is used, the light source retention system shall be designed with an indexing means so that the light source is properly indexed. Removable light source retention systems shall have an indexing feature so tha

13、t the light source cannot be reinserted into the lamp housing in a random position, unless the lamp will perform its intended function with random light source orientation. 6.5 Installation Requirements The side turn signal lamp shall meet the following requirements as installed on the vehicle. 6.5.

14、1 Visibility of each side turn signal lamp shall not be obstructed by any part of the vehicle throughout the photometric test pattern of Figure 1 unless the lamp is designed to comply with all photometric and visibility requirements with these obstructions considered. Figure 2 shows the range of the

15、 photometry test pattern. The visibility and photometric requirements below the lamp horizontal axis are not applicable when the lower lighted edge of the lamp is less than 750 mm above the ground. FIGURE 2 - VISIBILITY REQUIREMENTS SAE INTERNATIONAL J2039 Revised JAN2014 Page 8 of 9 6.5.2 All turn

16、signal lamps (direction-indicator lamps) on a vehicle shall be switched on and off by means of one control and shall flash at the same frequency and in phase with the required front and rear turn signal lamps. See SAE J1690 for flash rate and percent on time. 6.5.3 The side turn signal lamp shall be

17、 wired so that when it is in its flashing mode it shall continue to flash even with the vehicle brakes applied. 7. GUIDELINES 7.1 Installation Guidelines The following guidelines apply to side turn signal lamps as used on the vehicle and shall not be considered part of the requirements. 7.1.1 Perfor

18、mance of lamps may deteriorate significantly as a result of dirt, grime, snow, and ice accumulation on the optical surfaces. Installation of the device on the vehicle should be considered to minimize the effects of these factors. 7.1.2 Where it is expected that the device must perform in extremely s

19、evere environments, or where it is expected to be totally immersed in water, the user should specify devices specifically designed for such use. 7.1.3 The side turn signal lamp should be mounted; one on each side of the vehicle 12 m or more in overall length, with the optical center of the lamp moun

20、ted on or forward of the midpoint of the vehicle and at a height not less than 380 mm and not more than 1650 mm. 8.
